pyPDAF.PDAF.omi_init_obsvar_l_cb

pyPDAF.PDAF.omi_init_obsvar_l_cb()

This function is an internal PDAF-OMI function that is used as a call-back function to initialise local observation vector in domain localisation. This could be used to modify the observation variance when OMI is used with pyPDAF.PDAF.assimilate_xxx instead of pyPDAF.PDAF.omi_assimilate_xxx.

Parameters:

• domain_p (int) – Index of current local analysis domain

• step (int) – Current time step

• dim_obs_l (int) – Local dimension of observation vector

• obs_l (ndarray[tuple[dim_obs_l], np.float64]) –

  Local observation vector

  The array dimension dim_obs_l is Local dimension of observation vector.

• meanvar_l (float) – Mean local observation error variance

Returns:

meanvar_l – Mean local observation error variance

Return type:

float
